On the Performance of Redundant Traffic Elimination in WLANs
Redundant Traffic Elimination (RTE) detects and removes repeated chunks of data across network flows, protocols, and applications, with the purpose of reducing bandwidth usage. In this paper, the authors explore the effectiveness of RTE in WLAN, compare it to RTE in Ethernet, and investigate specific issues affecting RTE in WLAN. Their results show that applying RTE to WLAN links is promising and can potentially yield high bandwidth savings, although RTE is not as effective in WLAN as in wired networks. However, to exploit the full potential of RTE, it is necessary to deal with specific challenges, such as longer headers, control and management frames, retransmissions, and dropped frames.
